BOBBIN DRAG ARRANGEMENT FOR SPINNING AND LIKE TEXTILE FRAMES Original Filed Nov 19 ELL/WA Patented Sept. 6, 1932 FFICE ARTHUR LANGSTAFE BENSON, OF DUNDEE, ANGUS, SCOTLAND BOBBIN DRAG ARRANGEMENT FOR SPINNING AND LIKE TEXTILE FRAMES Original application filed November 19, 1930, Serial No. 496,583, and in Great Britain November 28, 1929.

Divided and'this application filed. September 17, 1931.

This invention relates to a bobbin-drag device for spinning, twisting, doubling, roving and like textile frames, so devised that the application of braking effort to the bobbin will not disturb the central position of the bobbin, it being understood that, when the bobbin is moved laterally against the spindle, as by certain existing drag devices, the tendency for the spindle to rotate the bobbin is still further increased.

The said drag device is particularly applicable to spinning and like frames embodying the features described in my co-pending application No. 496583 filed Nov. 19, 1930, of which the present application is a division.

The drag device according to the invention comprises a pair of diametrally opposed brake shoes engageable with the lower flange of the bobbin and connected to parallel bars operatively connected at two diametrally opposed points to a bobbin-receiving socket member rotatably mounted on the lifter, said bars beinng influenced by springs. With the described arrangement, as the socket rotates partially when frictionally entrained by the bobbin, it effects the spring-controlled movement of the shoes towards the bobbin flange. As the weight and speed of rotation of the bobbin increase with the amount of yarn being wound, the drag increases as the bobbin becomes filled.

In the drawing Figs. 1 and 2 are axial sections at right angles to one another and Fig. 3 is a plan view of a device embodying the invention.

As therein shown, the bobbin 7 strung on the spindle 3 is supported in a socket member 8 rotatably mounted on the lifter.

At diametrally opposed points the socket member 8 carries pins 9 engageable with two reversely bent parallel bars 10 each guided at the return bend over a pin 11 fitted to the lifter.

At one end each bar 10 is connected to a coil spring 12 anchored to the lifter. At its opposite upset end the bar has an ofl'set portion 10 to which is attached a floating block 14. Connected to the floating block 14 by pins 10 is a brake shoe 13 engageable with the usual groove in the bottom flange of the Serial No. 563,380.

bobbin. 15 denotes clips serving as anchorages for the springs 12 and embracing the flanges 16 of the lifter 17. i

It will be .seen that partial rotation of the socket 8 will efiect equal and opposite endwise movements of the bars 10 and cause simultaneous application or release of the brake shoes operative on diametrally opposed points of the bobbin.

l/Vhat I claim is In a spinning or like textile frame, a bobbin drag device comprising, in combination with a lifter, a bobbin-receiving socket member rotatably mounted on the lifter, parallel bars operatively connected to diametrally opposed points of said socket member, a pair of diametrally opposed brake shoes engageable with the lower flange of the bobbin and connected to said bars, and springs influencing said bars, whereby partial rotation of said socket member when frictionally entrained by the bobbin effects the spring controlled movement of said brake shoes towards the bobbin flange.

In testimony whereof I have signed my name to this specification.

ARTHUR LANGSTAFF BENSON.
